## Summary description

Three-phase automatic voltage regulator KEMOT PROavr-15k with 15 kVA rated power and 400 V nominal voltage. Designed to stabilize and protect electrical equipment from voltage fluctuations in industrial and commercial installations. Provides continuous automatic regulation for motors, pumps, compressors and sensitive electronics, improving reliability and reducing downtime.

## Long description

The KEMOT PROavr-15k automatic three-phase voltage regulator with 15 kVA rated power and 400 V nominal voltage is designed to stabilise and protect electrical equipment from mains voltage fluctuations. It provides continuous automatic regulation to maintain a stable 230 V output per phase (±3% in single-phase mode) and is suitable for industrial, commercial and household installations where reliable voltage quality is required.
Advantages
The stabiliser uses a toroidal transformer and servo-motor technology to achieve high output accuracy and smooth regulation. It can operate in single-phase mode with independent phase control or in three-phase mode with phase balance monitoring. Built-in protections include over- and under-voltage, overload, overheating and short-circuit protection. A bypass switch allows isolation of the stabiliser when needed, and a configurable DELAY (6–180 s) soft-start reduces risks from high inrush currents. Four sturdy wheels facilitate transport and positioning.
Suitable for
Electric motors, pumps and compressors
Office equipment: computers, monitors, printers, cash registers
Home appliances: induction hobs, microwave ovens, refrigerators and freezers
Audio/video equipment: TVs, speakers, mini-systems
Central heating pumps and stoves
Backup generators and other power equipment
Key specifications
Model: KEMOT PROavr-15k
Rated power: 15 kVA
Nominal voltage: 400 V (three-phase)
Output per phase: 230 V ±3% (single-phase regulation)
Regulation method: servo motor with toroidal transformer
Delay (soft-start) range: 6–180 seconds
Protections: over-voltage, under-voltage, overload, overheating, short-circuit, phase error detection
Bypass function: manual bypass switch
How to use
Install the stabiliser on a level surface and position it where wheels allow safe movement. Connect the three-phase input and output according to local electrical regulations and ensure proper grounding. Choose single-phase or three-phase operating mode as required. If connected loads have high starting currents, set the DELAY switch to an appropriate delay (6–180 s) before switching on to reduce inrush stress. Use the bypass switch when maintenance or direct mains feeding is required.
Usage recommendations
Regularly inspect electrical connections and ventilations openings, avoid placing the unit in direct sunlight or near heat sources, and observe the specified load limits. If a phase error is indicated, disconnect loads and check input phases before resuming operation.
